In the competitive world of paper manufacturing, achieving optimal strength and water resistance is paramount. Chemical auxiliaries play a crucial role, and among them, Styrene-Acrylamide Copolymers (often identified by CAS No. 24981-13-3) stand out as highly effective surface sizing agents. As a trusted manufacturer and supplier, we understand the critical needs of paper mills and are dedicated to providing innovative solutions.

Styrene-Acrylamide Copolymers are synthesized through a precise copolymerization process of styrene and acrylamide monomers. This results in a cationic polymer that exhibits exceptional film-forming capabilities. When applied to paper surfaces, these copolymers form a protective layer that significantly enhances hydrophobicity and improves the paper's resistance to water penetration. This not only leads to better print quality but also contributes to the overall durability of the paper product.

One of the key advantages of using these copolymers is their ability to work synergistically with starch. This allows for a reduction in the overall dosage of sizing agents required, thereby lowering production costs without compromising on quality. For paper manufacturers looking to buy these essential materials, sourcing from a reputable supplier is crucial. We ensure that our Styrene-Acrylamide Copolymer offers consistent performance, enabling paper mills to achieve superior ring-crush strength and improved surface characteristics in their board paper and corrugated paper products.

The application process is typically straightforward, with the copolymer being metered into the size press after starch cooking. Adjusting the pH with alum to the 3.5-4.0 range further optimizes its performance. This meticulous approach ensures that the cationic nature of the polymer is leveraged effectively, leading to better fiber bonding and enhanced paper properties. As a leading manufacturer in China, we are committed to providing high-quality chemical solutions that meet the evolving demands of the paper industry.
